Abstract

The utility model relates to a vertical annular-chamber return-flue water-heating boiler which is composed of a casing, an internal sleeve, a liner, a dry distillation preheating chamber, a high temperature smoke elimination chamber, a dust removal mouth, a steam pipe, a water inlet and a water outlet, a water nozzle, a thermometer seat, a water gauge seat, etc. The interior of the internal sleeve which is above a combustion chamber is provided with an annular-chamber return flue which is composed of a first flue, a second flue, and a third flue, wherein, the first and the second flues are annular long cylinders, and the interior of each flue is divided into symmetrical semicircle long cylinder flues. The design of the utility model fully uses energy, environmental pollution caused by black smoke is avoided, and the thermal efficiency is enhanced.

Description

Vertical ring casing backflow flue heat homogeneous solution-type reactor

The utility model relates to a kind of vertical type water heater boiler, particularly has the vertical type water heater boiler of ring casing backflow flue, belongs to the common mechanical field of engineering technology.

Traditional vertical type water heater boiler mostly is cylindrical space, and ectonexine is jacket structured, adorns water in the chuck, and the top is provided with flue.This design, flue gas flow is short, and heating surface area is little, and exhaust gas temperature is too high, a large amount of heat energy are directly discharged from flue, and boiler thermal output is reduced, and hydro-thermal gets slowly in the boiler, cause energy waste, in order to reduce thermal loss, what have has installed a plurality of pipes that are heated in upper boiler.But it is bigger to consume steel, and the cost height is made the system difficulty, incrustation scale easy-clear not in the pipe, and flue gas flow is short is not resolved, so DeGrain.

Also there is an obvious weak point in above-mentioned traditional vertical hot-water boiler structure, and promptly solid fuel ignition is insufficient, discharges a large amount of black smokes, has polluted environment.

The purpose of this utility model is: overcome the shortcomings and deficiencies that above-mentioned prior art exists, and a kind of hot-water boiler with vertical ring casing backflow flue is provided, to make full use of the energy, avoid the pollution of black smoke to environment, improve the thermal efficiency.

The purpose of this utility model is achieved through the following technical solutions:

Vertical ring casing backflow flue heat homogeneous solution-type reactor, comprise: shell, interior cover, inner bag, destructive distillation preheating chamber, high temperature smoke elimination chamber, fire door, fire bars, chimney, shoot door, dedusting mouth, steam pipe, water inlet, delivery port, Shui Zui, temperature meter base, water level meter seat, its feature is as follows:

In the cover ring casing backflow flue is arranged in above the combustion chamber, form by first flue, second flue and the 3rd flue, first flue and second flue are annular long column body, the interior semicircle long column body flue that is divided into symmetry by two baffle plates, the first flue bottom inlet communicates with the outlet of high temperature smoke elimination chamber, there is an aditus laryngis to communicate on its upper guard-plate with second flue is suitable for reading, two flue bottom inside have a under shed to communicate with central cylindrical the 3rd chimney intake, form ring casing backflow flue, flue gas is discharged from chimney at last.

The inboard of first flue and second flue and the 3rd flue outside form annular dress water inner bag.

Water inlet is installed in the shell below, is communicated with inner bag by below tube head endoporus, and delivery port is installed in the shell top, communicates with top tube head endoporus, and burned hot water from then on orifice flow goes out, and forming circulating water flow can be for heating.

The combustion chamber is divided into destructive distillation preheating chamber and high temperature smoke elimination chamber, by barrier partitions.

Owing to taked technique scheme, make the utility model compared with prior art, following advantage and effect are arranged:

1 owing to take ring casing backflow flue and annular inner bag, increased the heating surface area of body of heater, prolonged one times than the vertical boiler flue gas flow with volume, improves the thermal efficiency, fuel saving.

2 owing to taked the structure of destructive distillation preheating chamber and high temperature smoke elimination chamber, and it is indoor flourishing that flue gas that the new coal in the destructive distillation preheating chamber produces is eliminated smoke by high temperature, carries out burning the second time, and automatic smoke-eliminating has reduced environmental pollution.

3 make full use of heat and utilize heat for the second time.

4 speed of heating up water are fast, fast 2 times than conventional boiler speed.

5 owing to take ring casing backflow flue structure, makes in the stove flue dust by rising, descend, rise again and the aditus laryngis dilating effect being collected.

6 is simple in structure, easily manufactured, and scale removal is convenient.

Accompanying drawing of the present utility model and drawing explanation are:

Fig. 1 is a main pseudosection of the present utility model;

Fig. 2 is a side cutaway view of the present utility model;

Among the figure: 1 shoot door, 2 pallets, 3 destructive distillation preheating chambers, 4 new coals, 5 below tube head endoporus, 6 dust chambers, 7 shells, 8, second flue, 9 temperature meter bases, 10 interior covers, 11,13 the 3rd flues, 12 delivery port seats, 14 inner bags, 15 first flues, 16 dividing plates, high temperature smoke elimination chambers 17,18 is flourishing, 19 water inlet seats, 20 fire doors, 21 below tube head endoporus, 22 aditus laryngis, 23 steam pipes, 24 temperature meter bases, 25 dedusting mouths, 26 water are chewed, 27 under sheds, 28 cloths.

The utility model is described in further detail below in conjunction with drawings and Examples:

When using hot-water boiler to boil water, the delivery port pipe is closed, advance cold water from the bottom water inlet, when the indication of the water level meter on the water level meter seat reaches ordinary water level, some fuel, the direct radiation inner bag of combustion flame, make the water heating, and flue gas is discharged along ring casing backflow flue, and through the contrast experiment, the result shows: burn 500 kilograms of boiling water, use conventional boiler to need 60 minutes, 26 kilograms in consumption coal, the thermal efficiency 56%, and use the utility model boiler, only use 20 minutes, 12 kilograms in consumption coal, the thermal efficiency 86% economizes on coal 50%.

The utility model can be widely used in the northern area one-storey house, building is warmed oneself, heated up water or the like and uses.
